Yes. Enzymes lower the activation energy needed to start a chemical reaction so that they can occur at temperatures safe for the organism.
Enzymes are catalysts in a chemical reaction, they are used in chemistry to increase the speed of a specific chemical reaction. A single enzyme will not speed up multiple chemical reactions, usually it is limited to one reactant.
The reaction rate is affected by enzymes.
Correct. Enzymes help to speed up chemical reactions. They may speed them up, costing them some energy, but they are never used up.
Enzymes.
Enzymes lower the activation energy of a chemical reaction.
enzymes are never consumed in a chemical reaction, therefore the answer to your question is that enzymes that affect the speed of a chemical reaction without being consumed are indeed called enzymes.
No that is false. Enzymes do NOT increase number of collisions in a chemical reaction.
The Reaction Rate
Enzymes are catalysts and increase the speed of a chemical reaction without themselves .A chemical reaction can be represented by a chemical equation. An enzyme is a protein that speeds up a biochemical reaction .
No, enzymes are not permanently changed in the chemical reactions they are involved in. Enzymes are catalysts that facilitate chemical reactions by lowering the activation energy, and they remain unchanged after the reaction takes place. They can be used repeatedly in multiple reactions.
Enzymes are considered to be catalysts; they increase the rate of a chemical reaction.
Enzymes act as catalysts in biochemical reactions.
